Broadcast Target Re-level Calculator
Repurposing a mix between loudness standards? Pick source and destination spec — get the exact gain and the checks to re-run.
Assuming your mix sits exactly on its source target, moving between specs is a pure gain offset — R 128 → A/85 is just −1 dB. The traps are the destination's true-peak ceiling (checked here) and short-form rules (Max ST) that gain alone can't fix. Always re-measure after re-levelling.
